BACKGROUND OF THE PRESENT INVENTION

Field of Invention

The present invention relates to a safety device for vehicle, and moreparticular to a drunk driving prevention system and method, whichdetects the eye activity of the driver in the sense of determining thepresence of alcohol for indicating whether the driver is capable ofdriving the vehicle safely.

Description of Related Arts

Driving under the influence (DUI), commonly called “drunk driving”refers to operating a vehicle while one's blood alcohol content is abovethe legal limit set by state. Every year, ten thousands of people werekilled and more than hundred thousands of people were injured due todrunk driving. Every single injury and death caused by drunk driving istotally preventable. Recently, anti-drunk driving apparatuses toeliminate drunk driving are provided.

For example, an alcohol sensor is considered as one of the popularanti-drunk driving apparatuses to be installed into the vehicle, whereinwhen the driver is guided to blow a breath to the alcohol sensor, thealcohol sensor will measure the alcohol concentration. If the alcoholconcentration measured by the alcohol sensor is higher than apredetermined threshold, an ignition interlock is activated to stop theignition of the vehicle. In other words, the alcohol sensor can bedeactivated only when the alcohol concentration measured is below thepredetermined threshold to start the vehicle. However, such alcoholsensor has a drawback that even though the driver under the influencecan start and drive the vehicle by having other person to blow a breathto the alcohol sensor instead of the driver in order to deactivate thealcohol sensor.

The alcohol sensor is not accurate and will falsely determine thealcohol concentration of the driver by blown breath. For example, afterthe driver rinses his or her mouth in the morning by a mouth rinse whichcontains alcohol as one of the ingredients, the alcohol concentrationmeasured by the alcohol sensor will be higher than the predeterminedthreshold.

Furthermore, the drunk driver can cheat the alcohol sensor by any filterat the mouthpiece of the alcohol sensor when blowing the breath thereto.Therefore, the measured alcohol concentration by the alcohol sensor islower than the actuate alcohol concentration of the driver because ofthe filter.

The alcohol sensor can only stop the ignition of the vehicle. Once thevehicle is start, the drunk driver is able to drive the vehicle. Inother words, there is no prevention to stop the drunk driver whiledriving.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

The following description is disclosed to enable any person skilled inthe art to make and use the present invention. Preferred embodiments areprovided in the following description only as examples and modificationswill be apparent to those skilled in the art. The general principlesdefined in the following description would be applied to otherembodiments, alternatives, modifications, equivalents, and applicationswithout departing from the spirit and scope of the present invention.

Referring to FIG. 1 of the drawings, a drunk driving prevention systemaccording to a preferred embodiment of the present invention isillustrated, wherein the drunk driving prevention system comprises aneye symptom detector 10, a control module 20, and a signal module 30.The drunk driving prevention system can be installed into a vehicle thatthe drunk driving prevention system is electrically linked to a powersource of the vehicle such that when the vehicle is powered on, thedrunk driving prevention system will be automatically turned on.Alternatively, the drunk driving prevention system can be a self-powereddevice with battery installed and can be linked to the power source ofthe vehicle to ensure the synchronization between the drunk drivingprevention system and the vehicle. Preferably, the drunk drivingprevention system comprises a portable casing 101 to be supported at adesired location in the vehicle, wherein the eye symptom detector 10,the control module 20, and the signal module 30 are housed in theportable casing 101, as shown in FIG. 3.

According to the preferred embodiment, the eye symptom detector 10 isarranged for supporting at an interior of the vehicle at a position todetect eye symptoms of a driver. Preferably, the eye symptoms can be eyemovements of the driver and/or the eye vessels of the driver.

The eye movement refers to nystagmus which means fast and uncontrollablemovements of the eyes including horizontal nystagmus (side to side),vertical nystagmus (up and down), and torsional nystagmus (rotary). Inparticular, nystagmus is a term for involuntary jerking or bouncing ofthe eyeball. Accordingly, involuntary eye movements of nystagmus couldbe caused by excessive alcohol which influents the function of brain tocontrol eye movements.

The eye symptom detector 10 can be a video camera, a movement sensor, oran image capturer adapted for detecting the eye movements of the driver.Preferably, the eye symptom detector 10 is installed on a dashboard,rear view mirror, or a sun visor of the vehicle according to an eyelevel of the driver, as shown in FIG. 2.

In particular, the eye symptom detector 10 comprises an eyeball movementsensor 11 for detecting eyeball movements of the driver, a pupil sensor12 for detecting sizes of pupils of the driver, and an ocularconjunctival blood vessel capturer 13 for detecting the ocularconjunctival blood vessel, i.e. the diameter size of the ocularconjunctival blood vessel. Under the alcohol influence, the eyeballmovements are highly vulnerable and the pupils appear bigger and slower.Also, redness of the eyes is apparent. As a result, the eye movements ofa normal person are different from the eye movements of a drunk person.Furthermore, the eye symptom detector 10 can detect or capture thevessel diameter change, wherein the ocular conjunctival blood vesselswill dilate under alcohol influence.

The eye symptom detector 10 is activated in response to a start of thevehicle. When the driver sits at the driver side and/or when the vehiclekey is detected or inserted into the key ignition hole, the eye symptomdetector 10 will be automatically activated and will be automaticallysearching for the driver at the driver side of the vehicle. When twopersons are detected by the eye symptom detector 10, the signalgenerator 30 will generate a false signal so as to prevent any switchingbetween drivers.

The eye symptom detector 10 is deactivated once the vehicle is turnedoff. Therefore, the driver will be monitored during driving that the eyesymptom detector 10 will keep detecting the alcohol influenced eyesymptoms, including the eye movements and ocular conjunctival bloodvessels of the driver throughout the driving route. Since human bodywill take time to absorb and react with alcohol, the alcohol reaction,i.e. the control of eye movements or the dilatation of the ocularconjunctival blood vessel, will gradually appears. In this case, the eyesymptom detector 10 will monitor the eye movements and/or the diameterchange of the ocular conjunctival blood vessel of the driver in responseto the time factor of the alcohol influence.

According to the preferred embodiment, the control module 20 isoperatively linked to the eye symptom detector 10 for determining andanalyzing whether the eye symptoms of the driver match with the alcoholinfluenced eye symptoms. In other words, the eye symptom detector 10will determine and analyze whether the eye movements of the driver areinvoluntary eye movements that suspect an alcohol concentration of thedriver is above a predetermined threshold. Or, the eye symptom detector10 for will determine and analyze whether the diameter change of theocular conjunctival blood vessel that suspect an alcohol concentrationof the driver is above a predetermined threshold.

Accordingly, the control module 20 contains a plurality of differentthresholds to indicate different eye movements and different diameterchanges of the ocular conjunctival blood vessels. In particular, thecontrol module 20 comprises a memory unit 21 storing data of normal eyesymptoms, i.e. normal eye movements and normal diameter size of theocular conjunctival blood vessel, and a comparison unit 22 comparing thedetected eye symptoms by the eye symptom detector 10 to the normal eyesymptoms to determine whether the eye symptoms of the driver are alcoholinfluenced eye symptoms. In other words, the comparison unit 22 willcompare the detected eye movements by the eye symptom detector 10 to thenormal eye movements to determine whether the eye movements of thedriver are involuntary eye movements. The comparison unit 22 willcompare the detected ocular conjunctival blood vessel by the eye symptomdetector 10 to the normal ocular conjunctival blood vessel to determinewhether the diameter size of the ocular conjunctival blood vessel of thedriver is dilated.

The memory unit 21 will store the information of the eye symptoms ofdriver normally without alcohol influence. Preferably, under normalcircumstance (the driver without alcohol influence), the eye symptomdetector 10 will detect the normal eye symptoms of the driver duringdriving and will send the data of the normal eye symptom to the memoryunit 21 as a default setting. In other words, the eye symptom referenceof the driver is initially set in the memory unit 21. Therefore, the eyesymptom reference of the driver will include the normal eye movementsand normal ocular conjunctival blood vessel of the driver in the memoryunit 21. Therefore, when the eye symptom detector 10 detects the eyemovements of the driver, the comparison unit 22 will instantly comparethe detected eye symptoms to the eye symptom reference of the driver inorder to determine whether the eye symptoms of the driver are alcoholinfluenced eye symptoms. For example, when the eye symptom detector 10detects the eye movements of the driver, the comparison unit 22 willinstantly compare the detected eye movements to the normal eye movementsof the driver in order to determine whether the eye movements of thedriver are involuntary eye movements.

Preferably, a data of statistical normal eye symptoms, includingstatistical eyeball movements, statistical pupil sizes, and statisticalocular conjunctival blood vessel, are preset in the memory unit 21.Therefore, the comparison unit 22 will instantly compare the detectedeye movements to the statistical normal eye symptoms in order todetermine whether the eye symptoms of the driver are alcohol influencedeye symptoms.

According to the preferred embodiment, the drunk driving preventionsystem further comprises a facial recognition module 40 linked to thecontrol module 20 for capturing an image of the driver's face when theeye symptom detector 10 detects the eye movements of the driver. Thefacial recognition module 40 is preferably built-in with the eye symptomdetector 10, such that the facial recognition module 40 and the eyesymptom detector 10 are operated together to detect the image of thedriver's face and the eye movements of the driver at the same time.Accordingly, the image of the driver's face will be saved in the memoryunit 21. When the facial recognition module 40 captures the image of thedriver's face, the image of the driver's face will be locked to detectthe eye symptoms of the driver by the eye symptom detector 10.

It is worth mentioning that when the facial recognition module 40detects the driver as the owner of the vehicle, i.e. driving the vehiclefrequently, the memory unit 21 will be activated to the default setting.For example, the comparison unit 22 will instantly compare the detectedeye movements to the normal eye movements of the driver. If the facialrecognition module 40 detects a strange/new driver of the vehicle thatthe default setting does not contain the information of the new driver,the comparison unit 22 will instantly compare the detected eye movementsto the statistical normal eye movements.

According to the preferred embodiment, the control module 20 furthercomprises a sobriety test guidance 23 operatively linked to the eyesymptom detector for guiding the driver to perform a sobriety test whenthe eye symptom detector 10 detects the eye movements of the driver.Accordingly, the sobriety test is developed for the horizontal gazenystagmus to accurately identify possible drunk drivers.

In order to execute the sobriety test, the sobriety test guidance 23comprises a target object projector 231 provided at the eye symptomdetector 10. Preferably, the target object projector 231 is built-in atthe eye symptom detector 10 and is arranged for generating a light spoton the eye symptom detector 10. The target object projector 231 iscontrollably operated to move the light spot from one side to anotherwhile the eye symptom detector 10 will detect the eye movements of thedriver. Then, the comparison unit 22 will determine the angle at whichthe jerking movements begin by comparing with the normal eye movements.Researches proven that jerking movements in the eye before the gazereaches a 45-degree angle is indicative of a possible blood alcoholcontent level over 0.05%. Therefore, the jerking movements will be takenaccount of involuntary eye movements.

Preferably, the signal module 30 comprises a voice generator 31 forgenerating a voice signal to guide the driver to perform the sobrietytest. For example, a voice to remind the driver to focus on the lightspot by the target object projector 231 will be generated. The voicegenerator 31 will also generate a warning signal to notify the drivernot to drive the vehicle when alcohol influenced eye symptoms aredetected. The voice generator 31 can be wirelessly linked to the speakermodule of the vehicle as well.

As shown in FIG. 1, the signal module 30 further comprises an ignitiondeactivator 32 for operatively linking to an igniter of the vehicle,wherein when the alcohol influenced eye symptoms are determined, theignition deactivator 31 is activated for preventing an ignition of thevehicle. Therefore, once the alcohol influenced eye symptoms aredetermined, the driver is unable to start the vehicle. Likewise, if thedriver fails the sobriety test, the driver is unable to start thevehicle.

The signal module 30 further comprises a speed controller 33 foroperatively linking to the vehicle, wherein when the alcohol influencedeye symptoms are determined, the speed controller 33 is activated forcontrollably limiting the speed of the vehicle. Even though the drivermay force to start the vehicle, the speed of the vehicle will belimited, such as 5 mph, to prevent the over-speeding of the vehicle bythe drunk driver.

According to the preferred embodiment, the signal module 30 furthercomprises a communication unit 34 operatively linked to the control unit20, wherein the communication unit 34 is arranged for sending asuspected drunk driving signal to a police or a drunk driving controlorganization when the alcohol influenced eye symptoms are kept detectingfor a predetermined control time period, especially during driving. Thecommunication unit 34 can be a mobile communication network or awireless communication network linked to the closest police departmentor the drunk driving control organization. As it is mentioned above, theeye symptom detector 10 will be activated to continuously detect the eyesymptoms of the driver during driving. For example, when the alcoholinfluenced eye symptoms are kept detecting for one minute, the suspecteddrunk driving signal will be automatically sent by the communicationunit 34. In other words, even though the driver is able to start thevehicle at the time the driver has not been influenced by alcohol, theeye symptom detector 10 will continuously detect the alcohol influencedeye symptoms of the driver during driving to ensure there is no alcoholinfluence at all time. In some circumstances, the driver may drinkalcohol during driving. Therefore, the drunk driving prevention systemwill enforce the driver not to drive under alcohol influence duringdriving.

It is worth mentioning that the signal module 30 can be incorporatedwith a GPS module to provide location and time information of thevehicle. Therefore, polices or other enforcers can locate the vehiclewhen they receive the suspected drunk driving signal.

It is appreciated that the drunk driving prevention system can beenforced to be installed into the vehicle that the driver with arestricted license to go to and from work. When a person seats at thedriver side of the vehicle, the facial recognition module 40 will detectand recognize the person. If facial recognition module 40 recognizes theperson who is the driver with the restricted license, the control unit20 will execute the sobriety test for the driver and/or the eye symptomdetector 10 will be activated to detect the eye symptoms of the driver.Once the alcohol influenced eye symptoms are determined, the driver isunable to start the vehicle. The communication unit 34 willautomatically send the suspected drunk driving signal to the police orthe drunk driving control organization when the alcohol influenced eyesymptoms are detected. In addition, when the drunk driving preventionsystem is intentionally unplugged from the vehicle or broken, thecommunication unit 34 will instantly send the suspected drunk drivingsignal, especially when the driver is enforced with the restrictedlicense.

As shown in FIG. 4, the present invention further provides a drunkdriving prevention method for preventing drunk driving the vehicle,comprising the following steps.

(1) Detect eye symptoms of the driver by the eye symptom detector 10.Accordingly, when the vehicle is powered on, the eye symptom detector 10will automatically start to detect the eye symptoms of the driver.Concurrently, the facial recognition module 40 will automatically startto capture the image of the driver's face. In the step (1), the eyesymptoms of the driver are detected by the steps of detecting theeyeball movements of the driver via the eyeball movement sensor 11,detecting the sizes of pupils of the driver via the pupil sensor 12,and/or detecting the ocular conjunctival blood vessel.

Preferably, the sobriety test is executed for the driver by the sobrietytest guidance 23 of the control module 20 at the same time when the eyesymptom detector 10 detects the eye movements of the driver.

(2) Analyze whether the eye symptoms of the driver are alcoholinfluenced eye symptoms by the control module 20, accordingly, theinformation is retrieved from the memory unit 21, wherein the comparisonunit 22 will instantly compare the detected eye symptoms to the normaleye symptoms of the driver stored in the memory unit 21 in order todetermine whether the eye symptoms of the driver are alcohol influencedeye symptoms.

(3) If the eye symptoms of the driver detected are considered as normaleye symptoms, the driver is able to drive the vehicle. The driver isable to start the vehicle and drive. It is worth mentioning that the eyesymptom detector 10 will continuously detect the eye symptoms of thedriver during driving.

(4) Generate the drunk driving signal by the signal generator 30 if theeye symptoms of the driver detected to be alcohol influenced eyesymptoms that suspect an alcohol concentration of the driver is above apredetermined threshold. The drunk driving signal can be an ignitiondeactivating signal sent to the ignition deactivator 32 for preventingan ignition of the vehicle. The drunk driving signal can be a speedlimiting signal sent to the speed controller 33 to limit the speed ofthe vehicle. The driving signal can also be the suspected drunk drivingsignal sent by the communication unit 34.

It is worth mentioning that the drunk driving prevention system of thepresent invention can work in conjunction with breathalyzer to provide afurther indication of whether the driver is under the alcohol influence.

One skilled in the art will understand that the embodiment of thepresent invention as shown in the drawings and described above isexemplary only and not intended to be limiting.
